Atma-Sphere MP-1 inputs

Since the MP-1 only has 2 Aux inputs, and I already use them for CD and phono via an EAR 324 phono pre-amp, is there any issue with using the single-ended Tape loop input for a tuner?
I used the Tape Loop input for a source. I actually compared the sound versus the Aux1 and Aux2 inputs, and I could not detect a difference.

Go ahead and use it for the tuner.
Nope. I agree with Tvad. I use the single-ended tape loop as the input from my dac.

Thanks, Tvad and Duke. Will do.
